Remove unnecessary newlines...Text in gemtext is written in "long lines" - breaking up lines in the
gemtext file also breaks them up in the final output.
Update databases-getting-out-of-wack.gmi...Is there a need to manually truncate text lines in these files? I did that in this commit, but I don't really like doing it with regular text (it makes sense for code, but shouldn't text just wrap normally with screen size?).
